Ethylene polymers; in primary forms, n.e.c. in heading no. 3901

HS code 390190 covers a broad range of ethylene polymers in their primary forms, excluding those more specifically classified elsewhere in heading 3901. These polymers are essential materials in the plastics industry, with applications spanning packaging, construction, automotive, and numerous other sectors. As a versatile and widely-used group of thermoplastics, ethylene polymers under this code play a significant role in the global economy and international trade.

Ethylene polymers classified under HS code 390190 are typically produced through polymerization of ethylene gas. This process involves the use of catalysts to facilitate the linking of ethylene monomers into long polymer chains. The specific production techniques may vary depending on the desired properties of the final product, such as density, molecular weight, and degree of branching. Common methods include high-pressure, low-pressure, and solution polymerization, as well as copolymerization with other monomers.

The primary raw material for the production of ethylene polymers under HS code 390190 is ethylene gas, which is typically derived from the cracking of natural gas or petroleum. In addition to ethylene, the manufacturing process may require various catalysts, additives, and processing aids to achieve the desired polymer characteristics. Specialized production equipment, such as reactors, extruders, and pelletizers, are also essential inputs for this industry.

The ethylene polymers classified under HS code 390190 are used to manufacture a wide range of products, including films, sheets, pipes, containers, and various molded or extruded items. These polymers may be further processed or combined with other materials to create end-products that fall under other HS codes, such as 392010 Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 392020 Plates, sheets, film, foil and strip, of plastics, cellular, and 392030 Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials.
